Three-time Grammy winner singer Etta James, a pioneer of 1950s rhythm-and-blues and rock music known for her show-stopping hit “At Last”, died at the age of 73. With songs like “The Wallflower” and “Good Rockin’ Daddy”, the three-time Grammy winner was a key figure in the early days of rock ‘n’ roll, and her signature song, the 1961 ballad “At Last”, proved her mastery of the blues. She won her first Grammy in 1995 for her album, “Mystery Lady: The Songs of Billie Holiday”. She also won Grammys in 2003 and 2005, as well as a lifetime achievement award in 2003.
